0install 2.0 is out today. Zero Install is a decentralised cross-platform software installation system, allowing software developers to publish programs directly from their own websites, while still supporting shared libraries, automatic updates, dependency handling and digital signatures. It complements, rather than replaces, the OS' package management. Departing from its traditional use of installing desktop applications, many of the new features were driven by requirements from the Ryppl project, which is using 0install as the package manager in a modular build system for C++ projects.

The download worked fine for me. But so far (at least on Windows) I'm not impressed at all. The "catalog" has a bare handful of programs, several of which are already available via Ninite. The only advantage I see over the latter service is the ability to run the program before downloading. However, that's a pretty slim advantage until the catalog is expanded beyond a few games and random PC tools.

Clicked the link again from another browser and another internetconnection and still no download after 20 seconds. I am not going to use any "package manager" that cannot even get itself installed on my system
